SECFXCATION forming part of Letters Patent N o. 667,564, dated February 5, 1901.

Application led July 18, 1900. Serial No. 24:5032- (No model.)

To all wiz/0in 25 may concern:

Be it known that We, JOHN H. ODONNELL and WILLIAM D. PIERSON, of Waterbury, county of New Haven, State of Connecticut, have invented a new and useful Improvement in Wire-Drawing Machines, of which the following is a specication.

A machine embodying the improvement will be described in detail, and then the novel features will be pointed out in claims.

In the accompanying drawings, Figure lis a plan view of a machine embodying the improvement. Fig. 2 is a transverse section, upon an enlarged scale, upon the line 2 2 of Fig. l. Fig. 3 is a longitudinal section on the same scale as Fig. 2 on the plane of the dotted line 3 3 of Fig. 2. Fig. 4 is a side elevation of certain portions of the machine, including Stringing mechanism. Fig. 5 is a transverse section taken at the plane of the dotted line 5 of Fig. 4:.

Similar letters of reference designate corresponding parts in all the figures.

A designates a die-box comprising a number of die-holders a CL2, constructed to receive the dies through which the wire is passed. They are here shown as eight in number and are arranged in two rows, one rowin front of the other, the die-holders in each row being arranged opposite spaces between those of the other row. This die-box A is secured by screws or bolts a to the frame B of the machine. Forward of the die-holders are a number of drawing-rolls C C2 O3 C4 O5 C6 O7 C8. They are all Xed to a shaft O, journaled in the frame B of the machine.

Rearward of the die-box is a shaft D, which is jonrnaled in bearings in the frame B of the machine and has loosely mounted upon it, rearward of the die-box, a number of idlers D' D2 D3 D4 D5 D6 D?. The die-box A, the dra wing-rolls O' O2 O8 O4 O5 O6 O7 O8, and the idlers D D2 D3 D4 D5 D6 D7 all project over a tank E, in which a supply of liquid is maintained. At one end this tank is shown as provided with aloosely-turning roller e, having fianges near its ends. Over this roller the wire may pass to the first drawing-die, that die being contained in the rst die-holder a. Thence the wire passes a suitable number of times around the drawing-roll C. From that roll it passes back to and around the first idler D'. Thence it passes to the second drawing-die, that die being contained in the first die-holder a2. Thence it passes a suitable number of times around the drawing-roll C2, and from there passes backward, and after turning around the second idler D2 it passes into the third die, that die being supported in `the second die-holder a. Then it extends forward to the dra wing-roll C3, and after passing a suitable number of times around that drawing-roll it returns and passes around the third idler D3. From there it enters the fourth drawing-die, that die being inthe second dieholder a2. Then it passes a suitable number of times around the drawing-roll O4, returning thence to pass around the fourth. idler D4. From this idler it passes through the fifth drawing-die, that die being supported in the third die-holder a'. Thence it passes a suitable number of times around the drawing-roll O5, and returning passes around the fifth idler D5, so that it may pass forward and through the sixth drawing-die, that die being supported in the third die-holdera2.. Beyond the lastmentioned die-holder it extends through and around the drawing-roll C6. It returns from the latter to pass around the idler D5. Thence it passes through the seventh drawing-die, that die being supported in the fourth and last of the die-holders ct. Next it passes around the drawing-roll C7, and returning from there it passes around the seventh and last idler D7. Then it passes through the fourth and last of the drawing-dies in the holder a2 and forward to and around the eighth and last drawing roll O8. Subsequently it passes through-a die in a die-holder A, and thence it is taken up byawire block whose body is indicated by the dotted line F, carried by an upright shaft F', deriving motion through bevel gear-wheels f f2 from a horizontal shaft G. This shaft G is supported near one end by a bearing g, comprised in v9 adjusting wire blocks of different diameters into positions suitable for the last of the drawing-rolls C' C2 C3 C4 C5 C C7 C8, which may be in use at any time.

The shaft G has mounted upon it beyond the bearing g a gear-wheel 71,. In order to permit of the sliding of the shaft during adjustments of the slide g', it is necessary to connect it with the gear-wheel h by a feather or spline.

The gear-wheel 7L meshes with a gear-wheel h2, mounted upon a stud h3, which is adjustable in a slot made in the form of an arc concentric with the shaft G, so that the wheel h2 may be adjusted into dierent positions to permit the wheel h to be removed from the shaft G and another wheel of a different size arranged in its place to mesh with the gear- Wheel 71,2, all in a manner well known for change-gearing to provide for different speeds of the shaft Gr, suitable for wire blocks of different diameters. The gear-wheel h2 derives its motion from a gear-wheel h4, fixed to the shaft C.

The shaft C derives motion from a drivingshaft H, journaled in the frame B of the machine and having fixed to it a small gear or pinion h5. This gear-wheel h5 meshes with a gear-wheel 71,5, fixed to the shaft C.

Aiiixed to the shaft D, near one end, is a wheel-like portion I. Inside the rim portion is a metal clutch-strap t', pivotally connected at one end to an arm i by means of a pin ft2, which passes through a slot formed lengthwise in the arm, so as to aford the pin play in that direction. The arm is formed integral with an arm t3, and the piece of metal comprising these two arms is loosely mounted upon the hub of the part I.

Mounted loosely upon the shaft D, just beyond the wheel-like part I, is another wheellike part I. The arm t" extends below into both the parts I and I; but the arm 113 is wholly within the part I'. The hub formed with these two arms and mounted upon the hub of the part I is wholly within the part I'. A pin t4 extends from the arm i3 through a hole in the wheel-like part I, and also through a wire-gripping head J, its outer extremity being screw-threaded and fitted with a nut to secure it and the wire-gri ppin g head together. The shaft D extends beyond the hub, which is integral with the arms t" t3, into and through the wheel-like part I. Outside the latter the shaft is reduced in size and screw-threaded to receive a nut d for securing the wheel-like parts I and I in place.

The wire-gripping head J may be of any suitable construction, it being here shown as provided with inclined sliding jawsjj`, working in slideways formed in the head and normally impelled outward by a springj, so as to approach each other suiiciently to grip the wire. A handpiece L7'4 aiiords provision for conveniently moving the jaws inwardly, so that they will release the wire.

It has already been stated that one end of the strap t' is pivotally connected with the arm i. The other end of the strap is pivotally connected by a pin with a link t, and the latter is pivotally connected by a pin t7 with a lever i8, that is fulcrumed by a pin or screw t9 to the wheel-like part I. A lever is is bent so as to pass around the central hublike portion of the wheel-like part I. It is provided with apin 10, that extends through a slot 11 in the wheel-like part I. A

A die-rest K is supported by a rod k, which is pivoted by a pin k2 to a bracket k3, affixed to one end of the tank E. The bracket k3 is provided with a guide-wheel 7a4. A die to be threaded or strung upon the wire is first placed upon the wire by properly pointing the end of wire and passing said end through the die. Then it is placed upon the rod k while in a position to bear against the rear side of the die-rest K. The end of the wire is gripped by the jaws j' Q7'2. The attendant takes hold of the pin 10 and oscillates the lever 728, so that the latter will expand the strap t' against the inner Surface of the rim-like portion of the wheel-like part I. Then the arms il 'i3 will be locked to the wheel-like part I, so that they will participate in its rotary motion. Thus the wire-drawing head .I will be enabled to draw the wire through the die.` The Wire thus drawn will be wound upon the exterior of the wheel-like partsI I'. After a suicient quantity of wire shall have thus been drawn through the die the lever s will by manipulating the pin 10 be oscillated, so as to contract the strap t' for the purpose of disengaging the arms t" t3, and consequently the wire-drawing head J, from the wheel-like part I.

No mattei' what speed is given to the shaft C the shaft D will turn so slowly as to be well adapted for stringing dies upon wire to be drawn.

The die box A is provided practically throughout its length and width with a channel d, through which may be circulated any suitable cooling and lubricating liquid. Each of the die-holders a' a2 a3 a4 a5 a a7 a8 is a boxlike construction and has a suitable seat for a die. It is removably secured by screws or other means to the die-box. In Fig. 3 a die is shown in position in one of these die-holders, and it will be seen that opposite the opening of the die are vertical slots l Z2 for the passage of the wire. .In the bottom of each die-holder is a passage am, which communi- Cates with a channel a. The cooling and lubricating liquid passes up the passages aloof the various die-holders and rises into the dieholders until it reaches the wire for the purpose of cooling and lubricating it. Afterward it flows away. The liquid thus overflowing falls into the tank E, whence it is taken by a pump and delivered to a pipe au to again enter the die-box. The pipe a is provided with a cock w12 to control the flow of liquid through it.

Above each of the passages al is a deflector IOO IIO

eer/',564

@13, made in the form of a plate, fastened by a screw to the bottom of the die-holder and bent downwardly and notched suitably to eX- tend across such passage d10. The liquid in passing will be deected against the face of the die L for the purpose of lubrication and cooling.

What we claim as new, and desire to secure by Letters Patent, is-

1. In a wire-drawing machine the combination of a number of dies, anumber of rolls of different diameters affixed to a common shaft and serving to draw wire through said dies, a number of idlers around which such wire passes, a wire-Stringing device carried by the shaft supporting the idlers and gearing for rotating the said shaft at a suitablyslow speed for Stringing wire.

2. In a wire-drawing machine the combination of a number of dies, anumber of rolls for drawing wire through said dies, anumber of idlers around which such wire passes, a-

wire-Stringing device carried by the shaft supporting the idlers, and gearing for rotating the said shaft at a suitably-slow speed for Stringing wire, said gearing connecting said shaft with the shaft carrying the said rolls, so that the latter shaft while run at a high speed may transmit a slow speed to the shaft upon which the idlers and Stringing device are mounted.

3. In a wire-drawing machine the combination of a die-box provided with a passage for the circulation of liquid, separately-removable die-holders mounted upon the diebox and having passages communicating with the passage of the die-box, deectors adjacent the passages of the die-holders for deilecting liquid against the dies and means for drawing wire through the dies.

4. In a wire-drawing machine the combition of dies, means for drawing wire through the dies and a wire-Stringing device upon one of the shafts, said wire-Stringing device comprising a gripper for the wire, two wheel-like parts, one affixed to and the other loosely mounted upon a supporting-shaft, arms eX- tending from a loosely-mounted hub, and connected, one with the said wire-gripping device, a clutch-strap connected with the other arm, and a lever for expanding and contracting such clutch-band.

5. In a wire-drawing machine the combination of dies, means for drawing wire through the dies, and a wire-Stringing device upon one of the shafts, said wire-Stringing device comprising a gripper for the wire, two wheellike parts, one fixed to and the other loosely7 mounted upon a supporting-shaft, arms eX- tending from a loosely-mounted hub and connected one with said Wire-gripping device, and a strap connected with the other arm whereby the strap will be rendered operative by tension upon the wire-gripper.
